but when i want to run it, at horizon it come error :
Error: Failed to perform requested operation on instance "a", the instance has an error status: Please try again later [Error: Exceeded maximum number of retries. Exhausted all hosts available for retrying build failures for instance 42ad9bb0-8975-43a2-86d9-6101c0988925.].
please tell me what is the problem
i have already read at google.com, and he said its hardware problem :(Wed, 06 Feb 2019 04:00:02 -0600https://ask.openstack.org/en/question/119714/i-cant-run-instance/Comment by erchad for <p>i have already create instance,

https://ask.openstack.org/en/question/119714/i-cant-run-instance/?comment=119720#post-id-119720The error means that Nova found a compute node to run the instance, but it could not start it. You find more information in the nova-compute log, as Deepa says, but possibly also the nova-scheduler log.Wed, 06 Feb 2019 05:26:12 -0600https://ask.openstack.org/en/question/119714/i-cant-run-instance/?comment=119720#post-id-119720Comment by Deepa for <p>i have already create instance,

https://ask.openstack.org/en/question/119714/i-cant-run-instance/?answer=119742#post-id-119742I can't believe that you have no nova-scheduler log at all, and that your other logs only contain one message each.
In any case, this is obviously a misconfiguration. Have a look at nova.conf on the compute node(s): In the *[libvirt]* section, you will find a setting named *virt_type*. Correct it to be `kvm` instead of `kvm \n`.Wed, 06 Feb 2019 18:24:15 -0600https://ask.openstack.org/en/question/119714/i-cant-run-instance/?answer=119742#post-id-119742Comment by erchad for <p>I can't believe that you have no nova-scheduler log at all, and that your other logs only contain one message each.</p>
